Atomic Physics – X-rays
{"Image DocumentName": "Atomic Physics \u2013 X-rays", "Image ImageDescription": "The X-ray is emitted when an e from an n=4 states falls into the empty n=1 state. Ei= -13.6Z2/n2 = -(73)2(13.6 eV)/ 42. = eV. Ef= -13.6(73)2/12 = eV. hf = Ei- Ef= = eV = 67.9 keV. What is the wavelength?
